UPDATE: A group of 17 West Australians has flown out to help fight the bushfires burning across South Australia.
The group is made up of 12 people from the Department of Fire and Emergency Services, one volunteer from Jandakot Bush Fire Brigade and four representatives from the Department of Parks and Wildlife.
DFES Duty Assistant Commissioner Chris Arnol said the group would initially help by supporting the South Australian incident management team fighting the Eden Valley bushfire in the Barossa Valley.
“Over 2500ha of grassland and at least three homes have been destroyed by a fire burning in Eden Valley,” Mr Arnol said.
“Our team has been deployed to assist with the management of the emergency on a 12-hour shift rotation until the incident concludes.
“WA was asked to send assistance and, despite our own recent bushfires, WA personnel are always willing to help fellow firefighters in other States.”
The WA team is likely to be deployed for five days.
Twelves houses have been lost in South Australia's bushfires and authorities warn the number will rise.
Firefighters are still battling 10 fires across the State, with four of particular concern.
The Eden Valley fire has been upgraded to an Emergency warning level.
Just after 2pm (AEDT) the alert was issued as the fire burns out of control at Sugar Loaf Hill in the Barossa Valley.
The fire is travelling in a northerly direction towards Truro Road and the Sturt Highway.
The SA Country Fire Service advises there is a risk to lives and homes.
However, moderate weather conditions have allowed fire crews to gain the upper hand on some fires.
Watch and Act alerts remain in place for a blaze at Bangor in the southern Flinders Ranges.
Five homes have been lost in the blaze, which has burned through more than 22,000ha.
The same alert level has been issued for the Riverland complex fires, which may threaten safety at Calperum near Cooltong and Renmark West.
The CFS said seven homes were destroyed in the Billiatt and Eden Valley fires.
The CFS said 12 houses had been lost but that number could increase as damage assessment crews were deployed.
There had also been substantial stock losses.
South Australia Premier Jay Weatherill said it would be an achievement if the State came through the fires without loss of life or substantial property loss.
"It's an achievement which is entirely due to the professionalism and education of our emergency services," he said.
About 10 firefighters have been injured including for heat-related illness and smoke inhalation.
More than 30,000 lightning strikes across the State from noon on Friday created havoc for the firefighting effort.
The Bureau of Meteorology said weather conditions were moderating.
Victoria sent 10 CFA trucks to South Australia on Saturday to help with the bushfires.
